The 1989 Football League Third Division play-off Final was a two-legged football match played on 31 May and 3 June 1989, between Port Vale and Bristol Rovers to determine the third and final team to gain promotion from the Third Division to the Second Division. The top two teams of the 1988–89 Football League Third Division season gained automatic promotion to the Second Division, while those placed from third to sixth place in the table took part in play-offs; the winners of these semi-finals competed for the final place for the 1989–90 season in the Second Division. From 1990 onwards, play-off finals would be one-legged affairs decided at Wembley Stadium, or an appropriate neutral stadium.
